v BOOK Filed April 15, 1960 sa! e-W INVENTORS JOSEPH PUCCI THOMAS J. RYAN M Kw ATTORNEY 3,074,744 BOOK Joseph Pucci, .43 E. Wadsworth Ave, and Thomas J. Ryan, 426 E. Allens Lane, both of Philadelphia, Pa. Filed Apr. 13, 1960, Ser. No. 22,039 3 Claims. (Cl. 281-37) The present invention relates to books, and more particularly to books adapted to be used in arctic weather.

It has been found that the books, especially those used by the armed services as manuals, have not been satisfactory for use in arctic climate. The books and manuals used by the armed services in the arctic regions have not survived the extreme cold weather. The books used heretofore in the arctic regions, were of conventional construction having paper or heavy cardboard covers and backs. The paper and cardboard covers and backs become impregnated with moisture and crack or fall apart due to the extreme cold. Thus, it has been extremely difiicult and impractical to use the manuals and books of the armed services in arctic regions.

It is an object of this invention to overcome the disadvantages of the books and manuals which have been used in the arctic regions heretofore.

It is an object of this invention to provide a book which is not subject to being adversely affected by arctic weather.

It is an other object of this invention to provide a book which is easy to assemble and disassemble.

It is a further object of this invention to provide a book having novel flexible hinges.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 1 is a perspective view of the book of this invention in its closed disposition.

FIGURE 2 is a cross-sectional view taken along lines 2-2 of FIGURE 1.

FIGURE 3 is an exploded view of the book of this invention.

Referring to the drawing, where like numerals indicate like elements, there is shown a perspective view of the book of this invention.

Book 10 comprises a pair of side covers 12 and 16, a back 20 and a pair of hinges 22 and 24. As shown more clearly in FIGURES 2 and 3, the side cover 12 has a beaded edge 13. A hole 14 extends through the beaded edge 13 for its entire length. The hole 14 is provided with a slot 15 which extends to the periphery of the beaded edge 13. The slot 15 is in the same plane as the side cover 12.

Side cover 16 is provided with a beaded edge 17 having a hole 18 therethrough. The hole 18 is provided with a slot 19 which extends to the periphery of the beaded edge 17. The slot 19 is located in the same plane as the side cover 16.

The back 20 is slightly arched as shown in FIGURES 1 and 2, and is provided with beaded edges 26 and 28 extending along its sides. The beaded edges 26 and 28 are identical with the beaded edges 13 and 17 on the side covers 12 and 16, respectively. A pair of hinges 22 and 24 are provided to hold the side covers 12 and 16 and the back 20 in assembled disposition. The hinges 22 and 24 are identical, therefore it will be sufiicient to describe only hinge 22.

As seen more clearly in FIGURE 3, hinge 22 is an elongated member which is rectangular in shape. The beaded edges 36 and 32 extend along the sides of the 3,224,?44 Patented Jan. 22, 1963 ice hinge 22. The beaded edges 30 and '32 are of slightly smaller diameter than the holes 14 and 18. The thickness of the hinge 22 is slightly less than the width of the slots 15 and 19.

The hinge 22 operatively connects the side cover 12 and the back 20 as shown in FIGURE 2. The hinge 22 is made from a flexible material so that the side cover 12 may be pivoted to the position shown in phantom in FIGURE 2 as indicated by the arrow 34. In the same manner, hinge 24 operatively connects side cover 16 and back 20.

In order to make the side covers 12 and 16 and the back 20 durable and resistant to extremes in temperature, the side covers and the back are preferably made from metal or synthetic resins. It is proposed to make the side covers 12 and 16 and the back 20 from aluminum or a laminated synthetic resin such as nylon, Teflon, Kel-F, or polyethylene. Considerable research has been done in the field oflarninating nylon, and it has been found that such laminated structure is durable, resistant to extremes of temperature, and of suflicient light weight to be used as a book side cover. The hinges 22 and 24 should be made from a tough, flexible, synthetic resin such as nylon, woven fiberglass tape, Teflon, Kel-F, etc. The requirements for the material of the hinge are toughness and the ability to remain flexible at extreme tem- .peratures, that is extreme high and low temperatures.

The book is assembled in the following manner:

The side cover 12 and the back 26 are laid side by side and spaced apart the width of hinge 22. The hinge 22 is inserted endwise between the side cover 12 and the back 20 with the beaded edge 31 disposed within hole 14 and the beaded edge 32 disposed within the hole in the beaded edge 26 of back 20. The hinge 22 will extend through the slot 15 as shown more clearly in FKGURE 2. The hinge 24 is inserted into the beaded edges 17 and 2% in like manner. Then a leaf retainer 23 having a plurality of rings 25, 27 and 29 is atlixed to the inner surface of the back 20 for holding the leaves 36 in assembled disposition between the side covers 12 and 16. The retainer 23 for retaining the leaves 345 within the side covers 12 and 16 is known per se and is commercially available. The retainer 23 may be provided with a tab actuator 31 to cause the rings 25, 27 and 29 to open and close. Per se, the retainer 23 forms no part of the present invention. It is contemplated that a wide variety of means for retaining the leaves 36 in assembled disposition will be used.

For example, a conventional book binding wherein the pages are stitched together may be secured to the back 20 in any conventional manner.

If desired, the ends of the beaded edges 13, 17, 26 and 28 may be pinched so as to prevent the hinges from being withdrawn therefrom. Alternatively, adhesive may be applied to the inner surfaces of the holes in beaded edges 13, 17, 26 and 28 so as to retain the beaded edges on the hinges 22 and 24. The preferred embodiment contemplates a force fit between the beaded edges on the hinges 22 and 24 and the holes in the beaded edges 13, 17, 26 and 28. Thus, the preferred embodiment makes it possible for the easy removal and replacement of the covers 12 and 16 and the back 20. Thus, if one of the side covers is damaged, it is easily replaced. If the thickness of the book is to be increased, the back 20 may be easily removed and a new back of greater width may be substituted therefor.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
